I have several knives that I would like to store for at least 10 years. I know very little about knives. I've been told I could place them in an air tight bag, like a food saver bag, but I can't find where that's an acceptable way to store to store them. I don't know if this is the proper place to ask, but can someone give me some insight on long term knife storage? Or give me a URL to visit? I don't want to display them, just put them up for my kids. Thank you in advance for any assistance!!
